Fitting Polycarbonate Sheet Fixing Buttons
The following general pointers are offered to help you best fit the Polycarbonate Sheet Fixing Buttons:
- Use a sharp steel drill bit instead of a wood one
- Drill at least 40mm away from the edge
- Drill between the ribs
- Do not over-tighten the screw fixing and squash the sheets - as a guide the button should not touch the sheet
- Using an 18mm drill bit will allow the sheet to move due to natural expansion and contraction
- If using a large sheet the use of a purlin can be used.
- Use to fix into purlins, noggins or rafters.
